"Hi aridle
I bought one from the French Amazon site, it is of course written in French but I could manage to workout what info I needed.
You need to search for; Revue Technique automobile Fiat Ulysse. The publisher is E.T.A.I. the ISBN 2-7268-8559-4
Hope this is of some use.

I got my copy of this French manual yesterday (from Amazon.fr), and it looks useful.
For brake caliper torque settings, I posted this question a few months ago:
"Can anyone tell me the tightening torque for the front brake caliper bracket bolts on a 1996 Ulysse 1.9td ?"
and got this reply from carman:
"caliper to hub = 57 Nm
caliper to bracket 24 Nm"
I fitted my brake calipers to these torques, and 1400 miles later all seems well!
To help with the Lambda sensor, I'll have to have a look in the new manual and get back to you, unless anyone beats me to it.
When I changed my discs and pads it all went remarkably smoothly.
Best of luck.
